XA-768
Special Washer
SAF-Holland

A special washer designed to distribute load, prevent galling, and maintain preload in the clamp assemblies that secure hitch hardware. The washer’s size and geometry are chosen to accommodate the typical fasteners used with fifth-wheel brackets and plates, reducing concentrated stress that can lead to hardware failure under heavy loads. As part of the Component family, it complements other hardware in the mount assembly, providing a stable interface to the support structure and hitching surface. The VMRS code 053-007-008 places it among specialized washers used to ensure proper bearing surface and retention characteristics in heavy-duty towing systems. Category 42595 identifies this item as part of the broader component set that includes spacers, shims, and washers used to fine-tune fitment and alignment. In practical terms, technicians install this washer to improve clamp integrity, support even load transfer, and minimize the risk of fastener loosening due to dynamic forces encountered during road operation. This item is essential in maintaining long-term hitch reliability and repeatability of alignments.
